The present invention relates to a DNA fragment containing a nucleotide sequence that encodes an amino acid sequence of esterase, said esterase asymmetrically hydrolyzing carboxylic acid esters represented by the formula (I);
(wherein R₁ is alkyl, aralkyl or aryl, R₂ and R₃ are alkyl, and n is 1 or 2) an esterase encoded by the DNA fragment, a recombinant plasmid containing the DNA fragment, a microorganism transformed with the recombinant plasmid and methods of producing optically active carboxylic acids and their enantiomeric esters.
本发明涉及一种含有编码酯酶氨基酸序列的核苷酸序列的 DNA 片段,所述酯酶可不对称地水解式 (I) 所代表的羧酸酯;
(其中 R₁ 是烷基、芳基或芳基,R₂ 和 R₃ 是烷基,n 是 1 或 2)由该 DNA 片段编码的酯酶、含有该 DNA 片段的重组质粒、用该重组质粒转化的微生物以及生产光学活性羧酸及其对映体酯的方法。
